The battery lasts about 3 days
P.S. If don't know anything about phones or especially this phone don't post u'r opion
You won't find phones like this at this small price

Really like this phone... however really hope Siemens/ Benq will consider positioning ring tone speaker away from the receiver speaker for all their future models (where you place ear near the phone to listen to opposite party speak).... I nearly gone deaf for a couple of times...

Battery life to short 3 days max with very lighht use.
Software is not very intuative. anyways here is my story:

I live in Perth, western Australia, I bought my Siemens M65 at Singapore duty free airport , Within a month It started turning itself off so I logged a call with Siemens who said, I would have to send it to Singapore for repair, I had to explain that this is ridiculas, the phone is a month old and I live in Perth, if they do not support equipment bought at a duty free shop then they should not be allowing their equipment to be sold in them, anyways finally they allowed me to send my phone to a authorised repairer in Perth who had to send it to Sydney, after 4 weeks I got the phone back, straight away the signal was really bad and within a few days the phone started turning itself off again, rang repair shop they again sent it to Sydney 7 weeks later phone comes back, this time within a day, the phone turns itself off and won’t turn back on, I ring Siemens who say this time they will check that the phone has been repaired correctly.

This brings u up to date and I am about to go and get my phone repaired for the 3rd time, the phone has been with Siemens getting repaired longer than its been with me working. Yeah this phone is real rugged!.

Some additional points

The battery life is actually around 2 days with a max of 3 days if u do not use it.

The M65 is not always an M65, the M65 they sell in Singapore are actually cheaper models called M6C and M6V. The phone looks like an M65 and is badged as an M65 but once you check the product number using their software tool it tells u its different. When you go to there website for firmware updates it even asked you which Product you have. The choices are M65 M6V and M6C. How bad it that! you think your buying a M65 but your not, well you might be, you actually wont know until you open the box and check the product code hidden in the software.

I checked with the service centre and apparently a lot of companies do this, but Nokia and Sony/Ericson do not and that is why they can; and do provide international warranties, because they know that if one of there phones has a problem the same parts and software are contained within the phone, so any service centre will be able to fix it.

Hi, I'm Jeff from Indonesia, I've been using M65 for 1 yr. I'm a continuous users of M series (started from M35). From my experience as oil worker, this piece of craft is really something. For me it's not just shock proven, but "bang" proven. I've count 2 times it was slipped from my hand, fall from helideck to lowerdeck (about 7m) at my rig, and it still breath and sound :-D. Other phones might have been scattered :-)). I dont really care about MP3, bluetooth, etc. The only problem for me now,... I don't have enough reason to change to M75 :-)) I want to find the way how to properly make this M65 broken ^_^

This phone looks good and thats as far as it can get.Granted that the sound quality while talking is simply amazing. The goods stop there and the drawbacks start,when the phone memory is loaded fully its starts to hang,the only way it can recover is by pulling out the battery and putting it back again.

The shock proof thing is also not good,the protection gera come out once the phone has fallen out of youe lap when you get up more than thrice(mine did!).

So for all the people who want this as just a phone go ahead buy it,but youll find that it gets irritating using it after sometime.

I have a Siemens M65. The only thing i hate in it is that it lacks memory card. Can we use an attachable memory card? And can mp3 player be installed in it or not? Any one can email me, motasim_@hotmail.com
